The other part of the fix is in asm-powerpc/pgtable32.h. _PAGE_BASE needs _PAGE_COHERENT in order to work correctly, and in fact there is now a comment in there to that affect in 2.6.29. Backporting that change has made it work on 2.6.26. Both this patch, and the fix to head_32.S are needed for it to work correctly on older kernels. Chris
Hello Chris, sorry for dummy, but if it possible, could you, please, send a correspondin= g summary patch of backporting you've done for older kernels? or just summary of that changes once again? Many thanks Sergej.=
